天山北坡经济带是中国“一带一路”战略中最大的综合经济带，其绿色发展模式将为“一带一路”沿线国家实现区域绿色发展提供借鉴。本文采用绩效评估方法，从区域和产业两个维度对天山北坡经济带各经济区环境绩效进行评估，并根据评估结果将天山北坡经济带六个经济区划分为三翼：北翼（奎屯—克拉玛依—乌苏经济区）环境绩效最佳，南翼（伊宁—霍城—察布查尔经济区、乌鲁木齐—昌吉经济区、吐鲁番—哈密经济区）环境绩效其次，中翼（石河子—玛纳斯—沙湾经济区、博乐—精河—阿拉山口经济区）环境绩效较差。最后，基于环境绩效评估结果和区域产业发展定位，对三翼工业绿色发展提出战略建议。

The Tianshan Mountain Northern Slope Economic Belt is the largest economic belt in China, and is undergoing a development focus as part of the Belt and Road Initiative. Green development in this economic belt provides an important reference for other countries along the Belt and Road route. This study assesses the environmental performances of the Tianshan Mountain Northern Slope Economic Belt based on regional and industrial levels. Three wings of this economic belt—the south wing, middle wing, and north wing—are defined using the environmental performance assessment results. The environmental performance of the north wing (which includes the Kuytun–Karamay–Wusu economic zones) is best, followed by that of the south wing (which includes the Gulja–Korgas–Qapqel economic zones, the Urumqi–Changji economic zones, and the Turpan–Kumul economic zones). The environmental performance of the middle wing (which includes the Shihezi–Manas–Shawan economic zones and the Bortala–Jinghe–Alashankou economic zones) ranks lowest. Strategies for the green industrial development of these three wings are suggested based on the assessment results.
